DETAILED DESCRIPTION

In the following description of the various examples, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration various examples in which aspects of the disclosure may be practiced. It is to be understood that other examples may be utilized and structural and functional modifications may be made without departing from the scope and spirit of the present disclosure.

FIG. 1 depicts an isometric view of an insulating container 100, according to one or more aspects described herein. In one example, the container 100 may be configured to store a volume of liquid. The container 100 may comprise a canister 102 that is removably coupled to a spout adapter 104 and a lid 106. The lid 106, when removed from the spout adapter 104, may be configured to function as a cup into which, for example, a portion of the liquid stored in the canister 102 can be poured. In one example, the canister 102 may be substantially cylindrical in shape, however, it is contemplated that the canister 102 may be embodied with any shape, such as a cuboidal shape, without departing from the scope of these disclosures. Further, in various examples, the canister 102 may be referred to as a bottom portion, base, or insulated base structure having a substantially cylindrical shape.

FIG. 2 depicts another isometric view of the insulating container 100 from FIG. 1 , according to one or more aspects described herein. As depicted in FIG. 2 , the lid 106 is removed from the spout adapter 104 to reveal a cap 108 that is removably coupled to a top surface 110 of the spout adapter 104. The cap 108, when removed from the spout adapter 104, as depicted in FIG. 3 , reveals a spout opening 112 that extends through the spout adapter 104 into a cavity of the canister 102. Accordingly, the cap 108 may be configured to removably couple to, and seal (i.e. resealably seal), the spout opening 112. Accordingly, in one example, the spout opening 112 provides a narrower opening than an opening 158 (see, e.g. FIG. 9 ) of the canister 102, and as such, provides for more controlled/better targeted manual pouring of the contents of the canister 102 into another container, such as the lid 106, when removed from the spout adapter 104. In one example, the spout opening 112 of the spout adapter 104 is off-center on the top surface 110 of the spout adapter 104. It is contemplated that the spout opening 112 may be positioned at any point on the top surface 110, and may be off-center, as depicted, or may be centered. In another example, the spout opening 112 may have a central axis (parallel to the axis of rotation of the cylindrical shape of the spout opening 112) that is parallel to a longitudinal axis of the container 100 (i.e. longitudinal axis parallel to the axis of rotation of the cylindrical shape of the canister 102) and/or perpendicular to the plane of top surface 110 of the spout adapter 104. In an alternative example, the central axis of the spout opening 112 may be angled relative to the top surface 110 at an angle that is not 90 degrees. In this regard, it is contemplated that the any angle may be utilized, without departing from the scope of these disclosures.

In one implementation, the cap 108 includes a magnetic top surface 111. The magnetic top surface 111 may include a polymeric outer layer covering a ferromagnetic structure (e.g. a metal plate/other structural shape may be positioned below the magnetic top surface 111). In another implementation, all or a portion of the outer surfaces of the cap 108 may be constructed from one or metals and/or alloys. Accordingly, the magnetic top surface 111 may include an outer material that is ferromagnetic, or itself magnetized. In another implementation, the magnetic top surface 111 may comprise one or more polymers overmolded over a magnet structure (i.e. a magnetized metal/alloy may be positioned within the cap 108 as it is being molded).

The term “magnetic,” as utilized herein, may refer to a material (e.g. a ferromagnetic material) that may be temporarily or “permanently” magnetized. As such, the term “magnetic” may refer to a material (i.e. a surface, or object, and the like) that may be magnetically attracted to a magnet (i.e. a temporary or permanent magnet) that has a magnetic field associated therewith. In one example, a magnetic material may be magnetized (i.e. may form a permanent magnet). Additionally, various examples of magnetic materials may be utilized with the disclosures described herein, including nickel, iron, and cobalt, and alloys thereof, among others.

The cap 108, when removed from the spout opening 112, as depicted in FIG. 3 , may be magnetically coupled to a docking surface 114 of the spout adapter 104. Similar to the top surface 111 of the cap 108, the docking surface 114 of the spout adapter 104 may include a magnetic material. In one example, the docking surface 114 may include one or more polymers that are overmolded over a magnetic element (e.g. a metal plate, foil, or wire, among others). In another example, the docking surface 114 may include a metallic and magnetic outer surface.

It is contemplated that in one example, the canister 102 and the lid 106 may be primarily constructed from an alloy, such as steel, or an alloy of titanium, and the spout adapter 104 and cap 108 may be primarily constructed from one or more polymers (with the exception of the magnetic top surface 111, and the docking surface 114, among others). However, it is further contemplated that each element described herein can be constructed from one or more metals, alloys, polymers, ceramics, or fiber-reinforced materials, among others. In particular, the container 100 may utilize one or more of steel, titanium, iron, nickel, cobalt, high impact polystyrene, acrylonitrile butadiene styrene, nylon, polyvinylchloride, polyethylene, and/or polypropylene, among others.

FIG. 4 depicts an exploded isometric view of the container 100, according to one or more aspects described herein. In particular, FIG. 4 depicts the spout adapter 104 removed from the canister 102, and the lid 106 and cap 108 removed from the spout adapter 104. In one implementation, the spout adapter 104 may include a bottom threaded surface 116 that is configured to removably couple to a threaded inner surface 118 of the canister 102. Additionally, the spout adapter 104 may include a top threaded surface 120 that is configured to removably couple to a threaded inner surface of the lid 106. Further a threaded outer spout surface 122 is configured to removably couple to a threaded inner surface 124 of the cap 108.

It is contemplated, however, that in an alternative implementation, the threaded surfaces previously described may be reversed, without departing from the scope of these disclosures. In this alternative implementation, the spout adapter 104 may include a bottom threaded surface that is configured to removably couple to a threaded outer surface of the canister 102, and the spout adapter 104 may include a top threaded surface that is configured to removably couple to a threaded outer surface of the lid 106. Further a threaded inner spout surface of the spout opening 112 may be configured to removably couple to a threaded outer surface of the cap 108.

It is contemplated that a threaded surface discussed herein may include any thread geometry, including any thread pitch, angle, or length, among others, without departing from the scope of these disclosures. As such, any of the bottom threaded surface 116, threaded inner surface 118, top threaded surface 120, threaded inner surface of the lid 106, threaded outer spout surface 122, and/or threaded inner surface 124 may be fully engaged with corresponding mating elements by rotating the elements relative to one another by any number of rotations, without departing from the scope of these disclosures. For example, two mating threaded elements, from elements 116, 118, 120, 122, and/or 124, may be fully engaged by rotating by approximately ¼ of one full revolution, approximately ⅓ of one full revolution, approximately ½ of one full revolution, approximately 1 full revolution, approximately 2 full revolutions, approximately 3 full revolutions, at least 1 revolution, or at least five revolutions, among many others.

It is further contemplated that the removable couplings between one or more of the canister 102, the spout adapter 104, the lid 106 and the cap 108 may include additional or alternative coupling mechanisms, such as clamp elements, tabs, ties, or an interference fitting, among others, without departing from the scope of these disclosures.

FIG. 5 depicts a more detailed isometric view of the top of the spout adapter 104, according to one or more aspects described herein. The spout adapter 104 includes the bottom threaded surface 116 separated from the top threaded surface 120 by a grip ring 126. In one implementation, the docking surface 114 is formed from a portion of a handle 128 extending from the grip ring 126. In one implementation, the grip ring 126 is configured to be grasped by a user in order to couple and uncouple the spout adapter 104 from the canister 102 and/or lid 106. Accordingly, in one example, the handle 128 prevents or reduces a user's hand slipping around the grip ring 126 as a user exerts a manual torque on the spout adapter 104 to couple or decouple it from the canister 102 and/or lid 106. It is further contemplated that the grip ring 126 may comprise multiple handle structures in addition to the single handle 128 depicted in FIG. 5 , without departing from the scope of these disclosures. Additionally, the grip ring 126 may include one or more tacky or rubberized materials, or a surface texture such as a knurling, configured to prevent or reduce slippage of a user's hand as it rotates the spout adapter 104 relative to the canister 102 and/or the lid 106.

In one example, the spout opening 112 of the spout adapter 104 provides access to a spout channel 130 that extends through a height (approximately parallel to direction 132) of the spout adapter 104 and through to a bottom surface 134 of the spout adapter 104, as depicted in FIG. 6 . FIG. 7 schematically depicts a cross-sectional isometric view of the spout adapter 104, according to one or more aspects described herein. As depicted in FIG. 7 , the spout channel 130 may extend from the spout opening 112 through to the bottom surface 134. In the depicted implementation, the spout channel 130 may have a diameter 136 approximately uniform through the length of the spout channel 130. However, it is contemplated that the spout channel may have different diameters and sizes through the length of the channel extending between the spout opening 112 and the bottom surface 134.

In one implementation, the spout adapter 104 may include an internal cavity 138 that extends around the spout channel 130. This internal cavity 138 may be sealed by one or more manufacturing processes utilized to construct the spout adapter 104. Accordingly, in one example, the internal cavity 138 may contain a vacuum cavity to reduce heat transfer between the bottom surface 134 and top surface 111, or vice versa. Additionally or alternatively, it is contemplated that the internal cavity 138 may be partially or wholly filled with one or more foam or polymer materials to increase thermal resistance. In yet another example, one or more surfaces of the internal cavity 138 may be coated with a reflective material to reduce heat transfer by radiation.

In one example, a magnet, or magnetic material, may be positioned behind the docking surface 114. Accordingly, in one implementation, the magnet or magnetic material may be positioned within a cavity 140 within the handle 128. It is contemplated that any coupling mechanism may be utilized to position the magnet or magnetic material within the cavity 140, including gluing, an interference fitting, clamping, screwing, or riveting, among others. In another example, the magnet or magnetic material may be overmolded within the handle 128, and such that the cavity 140 represents a volume that the overmolded magnet or magnetic material occupies.

In one example, the spout adapter 104 may be integrally formed. In another example, the spout adapter 104 may be formed from two or more elements that are coupled together by another molding process, welding, gluing, interference fitting, or one or more fasteners (rivets, tabs, screws, among others). In one implementation, the spout adapter 104 may be constructed from one or more polymers. It is contemplated, however, that the spout adapter 104 may, additionally or alternatively, be constructed from one or more metals, alloys, ceramics, or fiber-reinforced materials, among others. The spout adapter 104 may be constructed by one or more injection molding processes. In one specific example, a multi-shot injection molding process (e.g. a two-shot, or a three-shot, among others) may be utilized to construct the spout adapter 104. It is further contemplated that additional or alternative processes may be utilized to construct the spout adapter 104, including rotational molding, blow molding, compression molding, gas assist molding, and/or casting, among others.

FIG. 8 depicts an isometric view of cap 108, according to one or more aspects described herein. As previously described, the cap 108 may include a magnetic top surface 111. Accordingly, the cap 108 may be constructed from one or more polymer materials, and such that the magnetic top surface 111 includes one or more polymers that are overmolded over a magnetic material.

In the depicted example, cap 108 has a substantially cylindrical shape. However, it is contemplated that additional or alternative shapes may be utilized, without departing from the scope of these disclosures. For example, cap 108 may be cuboidal in shape, among others. The cap 108 includes grip depressions 142 a-c, which are configured to reduce or prevent a user's fingers from slipping upon application of a manual torque to the cap 108 to couple or uncouple the cap 108 to or from the threaded outer spout surface 122 of the spout opening 112. It is contemplated that any number of the grip depressions 142 a-c may be utilized around a circumference of the cylindrical cap 108, without departing from the scope of these disclosures. Further, the cap 108 may include additional or alternative structural elements configured to increase a user's grip of the cap 108. For example, an outer cylindrical surface 144 of the cap 108 may include a tacky/rubberized material configured to increase a user's grip. Further, the outer cylindrical surface 144 may include a series of corrugations, or a knurling.

FIG. 9 schematically depicts a cross-sectional view of the insulating container 100 with the cap 108 coupled to the threaded outer spout surface 122, the lid 106 coupled to the top threaded surface 120 of the spout adapter 104, and the bottom threaded surface 116 of the spout adapter 104 coupled to the threaded inner surface 118 of the canister 102.

The canister 102 may include a first inner wall 146 and a second outer wall 148. A sealed vacuum cavity 150 may be formed between the first inner wall 146 and the second outer wall 148. This construction may be utilized to reduce heat transfer through the first inner wall 146 and the second outer wall 148 between a reservoir 152, which is configured to receive a mass of liquid, and an external environment 154. As such, the sealed vacuum cavity 150 between the first inner wall 146 and the second outer wall 148 may be referred to as an insulated double-wall structure. Additionally, the first inner wall 146 may have a first end 156 that defines an opening 158 extending into the internal reservoir 152 for receiving a mass of liquid. The second outer wall 148 may form an outer shell of the canister 102. The second outer wall 148 may be formed of a side wall 160 and a bottom portion 162, which forms a second end 164 to support the canister 102 on a surface. A seam 163 can be formed between the second outer wall 148 and the bottom portion 162. In one example, the bottom portion 162 can be press-fitted onto the second outer wall 148. Additionally the bottom portion 162 can be welded to the second outer wall 148. The weld may also be polished such that the seam does not appear on the bottom of the canister 102.

The bottom portion 162 may include a dimple 166 that is used during a vacuum formation process. As depicted in FIG. 9 , the bottom portion 162 may cover the dimple 166 such that the dimple 166 is not visible to the user. The dimple 166 may generally resemble a dome shape. However, other suitable shapes are contemplated for receiving a resin material during the manufacturing process, such as a cone, or frustoconical shape. The dimple 166 may include a circular base 168 converging to an opening 170 extending into the second outer wall 148. As discussed below, the opening 170 may be sealed by a resin (not shown). During the formation of the vacuum between the first inner wall 146 and the second outer wall 148, the resin may seal the opening 170 to provide the sealed vacuum cavity 150 between the first inner wall 146 and the second outer wall 148 in formation of the insulated double-wall structure.

In alternative examples, the dimple 166 may be covered by a correspondingly shaped disc (not shown) such that the dimple 166 is not visible to the user. The circular base 168 may be covered by a disc, which can be formed of the same material as the second outer wall 148 and the first inner wall 146. For example, the first inner wall 146, the second outer wall 148, and the disc may be formed of titanium, stainless steel, aluminum, or other metals or alloys. However, other suitable materials and methods for covering the dimple 166 are contemplated, as discussed herein and as discussed in U.S. Appl. No. 62/237,419, which is incorporated fully by reference as set forth fully herein.

The canister 102 may be constructed from one or more metals, alloys, polymers, ceramics, or fiber-reinforced materials. Additionally, canister 102 may be constructed using one or more hot or cold working processes (e.g. stamping, casting, molding, drilling, grinding, forging, among others). In one implementation, the canister 102 may be constructed using a stainless steel. In specific examples, the canister 102 may be formed substantially of 304 stainless steel or a titanium alloy. Additionally, one or more cold working processes utilized to form the geometry of the canister 102 may result in the canister 102 being magnetic (may be attracted to a magnet).

In one example, the reservoir 152 of the canister 102 may have an internal volume of 532 ml (18 fl. oz.). In another example, the reservoir 152 may have an internal volume ranging between 500 and 550 ml (16.9 and 18.6 fl. oz.) or between 1000 ml and 1900 ml (33.8 fl. oz. and 64.2 fl. oz). In yet another example, the reservoir 152 may have an internal volume of at least 100 ml (3.4 fl. oz.), at least 150 ml (5.1 fl. oz.), at least 200 ml (6.8 fl. oz.), at least 400 ml (13.5 fl. oz.), at least 500 ml (16.9 fl. oz.), or at least 1000 ml (33.8 fl. oz.). The opening 158 in the canister 102 may have an opening diameter of 64.8 mm. In another implementation, the opening 158 may have an opening diameter at or between 60 and/or 70 mm. The reservoir 152 may have an internal diameter 153 and a height 155 configured to receive a standard-size 355 ml (12 fl. oz.) beverage (aluminum) can (standard 355 ml beverage can with an external diameter of approximately 66 mm and a height of approximately 122.7 mm). Accordingly, the internal diameter 153 may measure at least 66 mm, or between 50 mm and 80 mm. The height 155 may measure at least 122.7 mm, or between 110 mm and 140 mm.

Additional or alternative methods of insulating the container 100 are also contemplated. For example, the cavity 150 between the first inner wall 146 and the outer walls 148 may be filled with various insulating materials that exhibit low thermal conductivity. As such, the cavity 150 may, in certain examples, be filled, or partially filled, with air to form air pockets for insulation, or a mass of material such as a polymer material, or a polymer foam material. In one specific example, the cavity 150 may be filled, or partially filled, with an insulating foam, such as polystyrene. However, additional or alternative insulating materials may be utilized to fill, or partially fill, cavity 150, without departing from the scope of these disclosures.

Moreover, a thickness of the cavity 150 may be embodied with any dimensional value, without departing from the scope of these disclosures. Also, an inner surface of one or more of the first inner wall 146 or the second outer wall 148 of the container 100 may comprise a silvered surface, copper plated, or covered with thin aluminum foil configured to reduce heat transfer by radiation.

In one example, the lid 106 may be formed of one or more metals, alloys, polymers, ceramics, or fiber-reinforced materials, among others. Further, the lid 106 may be formed using one or more injection molding or other manufacturing processes described herein among others. The lid 106 may comprise a solid structure, or may include a double-wall structure similar to the canister 102, having an inner wall 172, an outer wall 174, and a cavity 176 therebetween. It is also contemplated that the lid 106 may be insulated such that the cavity 176 is a vacuum cavity constructed using the techniques described herein.

In one example, the canister 102 includes a shoulder region 182. As such, the canister 102 may have an outer diameter 184 that is greater than an outer diameter 186 of the spout adapter 104. Accordingly, an outer wall 148 of the canister 102 may taper between points 188 and 190 along a shoulder region 182. In one example, the shoulder region 182 may improve heat transfer performance of the canister 102 (reduce a rate of heat transfer). In particular, the shoulder region 182 may comprise insulation having lower thermal conductivity (higher thermal resistance/insulation) than the lid spout adapter 104 that seals the opening 158.

It is contemplated that the spout adapter 104 may include a lower gasket 178 configured to seal the opening 158 of the canister 102 when the spout adapter 104 is removably coupled thereto. Additionally, the spout adapter 180 may include an upper gasket configured to resealably seal the lid 106 against the spout adapter 104, when coupled thereto.

FIGS. 10A-10F depict steps of a molding process of the spout adapter 104, according to one or more aspects described herein. As previously described, the spout adapter may be constructed from one or more polymers, and molded using a multi-shot injection molding process, among others. Accordingly, in one example, FIG. 10A depicts an intermediate spout adapter structure 1002 of following a first injection molding shot of polymer. The intermediate spout adapter structure 1002 includes a top threaded section 1004 and a bottom threaded section 1006 that will form the top threaded surface 120 and the bottom threaded surface 116, respectively, when the molding processes of the spout adapter 104 are complete. In one implementation, the intermediate spout adapter structure 1002 includes a complete top surface 110 and spout opening 112 having threaded outer spout surface 122 and spout channel 130.

FIG. 10B depicts a second intermediate spout adapter structure 1010 following a second injection molding shot. The second intermediate spout adapter structure 1010 includes a grip ring base structure 1112 that extends around a circumference of the second intermediate spout adapter structure 1010 and forms an underlying structural support surface for an overmolded third shot that forms the grip ring 126, as described with reference to FIG. 10C. Additionally, the second intermediate spout adapter structure 1010 includes a handle base structure 1114, which forms an underlying structural support surface for an overmolded third shot that forms the handle 128. Further, the handle base structure 1114 includes a plate bracket 1116, which, in one implementation, is configured to hold a magnetic plate 1118 in a fixed position on surface 1120 prior to overmolding to form the docking surface 114. Further, the plate bracket 1116 may include clamping elements configured to hold the magnetic plate 1118 in an interference fit prior to overmolding with a third injection molding shot. However, it is contemplated that the plate bracket 1116 may utilize additional or alternative elements for holding the magnetic plate 1118, including gluing, or using one or more fasteners, among others.

FIG. 10C depicts a third intermediate spout adapter structure 1020 following a third injection molding shot of polymer. In particular, a third injection molding shot of polymer is configured to overmold the grip ring base structure 1112 and handle base structure 1114 to form the grip ring 126 and handle 128 with docking surface 114, as previously described. It is also contemplated, however, that the grip ring base structure 1112 could be formed separately with threads and threaded and glued into place on the spout adapter structure 1010.

FIG. 10D depicts a bottom view of the third intermediate spout adapter structure 1020 of FIG. 10C. In particular, FIG. 10D depicts an opening 1022 into a cavity (i.e. cavity 138 described in FIG. 7 ) prior to forming the bottom surface 134 of the spout adapter 104. Accordingly, a foam 1024 may be injected into the cavity, as depicted in FIG. 10D to partially or wholly fill the cavity, and thereby increase thermal resistivity of the spout adapter 104, once complete. It is contemplated that the foam 1024 may comprise any polymer foam material, without departing from the scope of these disclosures.

FIG. 10E depicts a fourth intermediate spout adapter structure 1030 having a lower cap 1032 positioned to cover the opening 1022, as previously described in relation to FIG. 10E. In one example, the lower cap 1032 may be formed by a fourth shot of a polymer injection molding process (otherwise referred to as a first shot of a process to mold the bottom surface 134).

FIG. 10F depicts the complete spout adapter 104 following a fifth shot of an injection molding process (otherwise referred to as a second shot of a process to mold the bottom surface 134). As depicted, a fifth injection molding shot may be utilized to mold a sealing element 1042, which seals the opening 102, as previously described in relation to FIG. 10E, and forms the bottom surface 134 of the complete spout adapter 104.

FIG. 11 depicts an isometric view of an opening adapter assembly 1100 configured to be removably coupled to an insulating container, according to one or more aspects described herein. In one example, the opening adapter assembly 1100 may be configured to be removably coupled to the insulating container canister/bottle 102, as previously described in these disclosures. FIG. 12 depicts an exploded isometric view of the opening adapter assembly 1100 from FIG. 11 , according to one or more aspects described herein. In one example, the assembly 1100 includes a lid 1202. This lid 1202 may be similar to lid 106. Further, the lid 1202 may be configured to be removably coupled to an opening adapter 1204. In one example, the opening adapter 1204 may have a substantially cylindrical geometry with an external top threaded surface 1220 that is configured to engage with internal threads of the lid 1202. Additionally, the opening adapter 1204 may include an external bottom threaded surface 1222 that is configured to engage with a threaded inner surface of a canister, such as surface 118 of canister 102. An upper gasket 1208 and a lower gasket 1210 may be configured to seal an opening of the canister 102 when the external bottom threaded surface 1222 is removably coupled thereto. Further, the upper gasket 1208 and the lower gasket 1210 may include any gasket geometry and/or materials, without departing from the scope of these disclosures.

A grip ring 1206 may extend around a circumference of the opening adapter 1204. The grip ring 1206 may be spaced between the external top threaded surface 1202 and the external bottom threaded surface 1222. In one example, the grip ring 1206 may be integrally molded with the cylindrical structure of the opening adapter 1204. In another example, the grip ring 1206 may be formed separately, and rigidly coupled to the cylindrical structure of the opening adapter 1204. For example, the grip ring 1206 may be injection molded as a separate element and subsequently coupled to the opening adapter 1204 by gluing, welding, and/or an interference fitting, among others. In another example, the grip ring 1206 may be overmolded onto the opening adapter 1204.

The opening adapter 1204 may include a top opening 1224 configured to receive a plug structure 1212. The plug structure 1212 may include a bottom portion 1216 that has a substantially cylindrical sidewall, and a top portion 1214 that is rigidly coupled thereto. In one example, the bottom portion 1216 may be spin welded to the top portion 1214, among others. FIG. 13 depicts another isometric view of the plug structure 1212, according to one or more aspects described herein. In one implementation, the substantially cylindrical sidewall of the bottom portion 1216 of the plug structure 1212 may include a threaded outer surface 1302 that is configured to removably couple to the internal threaded surface 1218 of the opening adapter 1204. In one example, the plug structure 1212 may be configured to resealably seal the top opening 1224 of the opening adapter 1204 when the threaded outer surface 1302 engages with the internal threaded surface 1212 of the opening adapter 1204. Further, the top portion 1214 may be configured to extend, in a radial direction, beyond the sidewall of the bottom portion 1216 to form a sealing surface 1304. This sealing surface 1304 may be configured to abut a top lip of the opening adapter 1204 at the top opening 1224. Accordingly, the sealing surface 1304 may include a gasket, and this gasket may have any geometry (e.g. c-shaped gasket, among others), and may be constructed from any material, without departing from the scope of these disclosures.

The plug structure 1212 may include a handle 1306 that is rigidly coupled to the top portion 1214. The handle 1306 may extend across a diameter of the top portion 1214, and may be configured for manual actuation of the threaded coupling between the plug structure 1212 and the opening adapter 1204, as well as for manual insertion/removal of the plug structure 1212. The plug structure 1212 may also include one or more external channels 1308. In one specific example, the plug structure 1212 may include three external channels 1308 equally spaced apart around a circumference of the outer sidewall of the bottom portion 1216 of the plug structure 1212. It is contemplated, however, that any number of external channels 1308 may be utilized, without departing from the scope of these disclosures. The external channel 1308 may be configured to extend between a channel top edge 1310 and a channel bottom edge 1312. In one implementation, a depth of the external channel 1308 (e.g. depth along a radial direction relative to the substantially cylindrical geometry of the outer sidewall of the bottom portion 1216 of the plug structure 1212) may be uniform along a longitudinal length of the external channel 1308 (e.g. along that direction parallel to a longitudinal axis of the cylindrical geometry of the bottom portion 1216 of the plug structure 1212). In another implementation, a depth of the external channel 1308 may be non-uniform, and may transition from a first depth to a second depth, less than the first depth, along a channel transition region 1314. In certain examples, the external channel 1308 may be configured to provide a partial or full gas pressure relief/equilibration between an external environment and an internal compartment of the canister 102 that the opening adapter 1204 is removably coupled to.

In one example, the plug structure 1212 may include an internal cavity that is partially or wholly filled with an insulating material, such as a foam (e.g. expanded polystyrene, among others), and/or may include a vacuum cavity, configured to reduce heat transfer therethrough.

The plug structure 1212 may additionally include retention tabs 1316. As depicted, the plug structure 1212 may include three retention tabs 1316 equally spaced around a circumference of a base 1318 of the plug structure 1212. However, it is contemplated that any number of retention tabs 1316 may be utilized, without departing from the scope of these disclosures. In one example, the retention tabs 1360 may include flexures (e.g. one or more of longitudinal surface 1322 and/or radial surface 1320 may be configured to deform) configured to flex between a compressed configuration and an expanded configuration. As depicted in FIG. 13 , the retention tabs 1316 are in the expanded configuration.

In one example, the retention tabs 1316 may be configured to limit the extent to which the plug structure 1212 may be removed from the opening adapter 1204 when the threaded outer surface 1302 is uncoupled from the internal threaded surface 1218 of the opening adapter 1204. In particular, when in the expanded configuration, the retention tabs 1316 may be configured to abut a retention surface of the opening adapter 1204. As such, FIG. 14 depicts a bottom view of the opening adapter 1204, according to one or more aspects described herein. In one implementation, the retention tabs 1316 may be configured to abut the retention ridge surface 1402 of the opening adapter 1204 when in the expanded configuration.

FIG. 15A schematically depicts a cross-sectional view of the plug structure 1212 when fully engaged with the opening adapter 1204. In particular, FIG. 15A schematically depicts the threaded outer surface 1302 of the plug structure 1212 coupled to the internal threaded surface 1218 of the opening adapter 1204. Further, when in this depicted fully engaged configuration, the retention tab 1316 may be spaced apart from the retention ridge surface 1402 of the opening adapter 1204. FIG. 15B schematically depicts another cross-sectional view of the plug structure 1212 in a partially uncoupled configuration relative to the opening adapter 1204. Accordingly, as depicted in FIG. 15B, the threaded outer surface 1302 of the plug structure 1212 may be uncoupled from the internal threaded surface 1218 of the opening adapter 1204. However, the plug structure 1212 may be prevented from being fully removed from the opening adapter 1204 as a result of the retention tab 1316 abutting the retention ridge surface 1402 of the opening adapter 1204. Advantageously, this partial uncoupling may allow for the top opening 1224 to be unsealed, and the contents of, in one example, the canister 102 to be poured therefrom, without the plug structure 1212 being fully removed from the opening adapter 1204. Further advantageously, this functionality may allow for single-handed actuation of the threaded coupling between the opening adapter 1204 and the plug structure 1212, as well as pouring of the contents of the canister 102, without requiring the plug structure 1212 to be fully removed and held in a user's other hand, or set aside on an external surface.

In order to fully remove the plug structure 1212 from the opening adapter 1204, a manual decoupling force may be applied to urge the retention tabs 1316 to transition from the expanded configuration depicted in FIG. 15B, to a compressed configuration that allows the retention tabs 1316 to move past the retention ridge surface 1402. In one example, this manual decoupling force may be applied in a direction parallel to a longitudinal axis of the cylindrical structure of the bottom portion 1216. It is contemplated that any decoupling force may be utilized, based on the specific geometries and materials, among others, of the retention tabs 1316, without departing from the scope of these disclosures. Additionally or alternatively, the retention tabs 1360 may be configured to abut one or more additional or alternative surfaces of the opening adapter 1204 when in the expanded configuration, such as base surface 1502, without departing from the scope of these disclosures.

It is contemplated that the structures of the opening adapter assembly 1100 may be constructed from any materials. For example, one or more of the described elements may be constructed from one or more polymers, metals, alloys, composites, ceramics or woods, without departing from the scope of these disclosures. In particular, the opening adapter assembly 1100 may utilize one or more of steel, titanium, iron, nickel, cobalt, high impact polystyrene, acrylonitrile butadiene styrene, nylon, polyvinylchloride, polyethylene, and/or polypropylene, among others. It is further contemplated that any manufacturing methodologies may be utilized to construct the described elements of the opening adapter assembly 1100, without departing from the scope of these disclosures. In certain examples, injection molding, blow molding, casting, rotational molding, compression molding, gas assist molding, thermoforming, or foam molding, welding (e.g. spin welding), gluing, or use of fasteners (e.g. rivets, staples, screws etc.) among others, may be utilized, without departing from the scope of these disclosures. Additionally, it is contemplated that the depicted and described elements of the opening adapter assembly 1100 may be constructed with any dimensional values, without departing from the scope of these disclosures. As such, for example, the described threads (e.g. of threaded outer surface 1302, internal threaded surface 1212, external top threaded surface 1220, and/or external bottom threaded surface 1222) may be constructed with any thread geometries, without departing from the scope of these disclosures.

In one example, an insulating container formed of a material can include a canister that has a first inner wall that has a first end with a threaded sidewall and an opening extending into an internal reservoir for receiving liquid, and a second outer wall forming an outer shell of the canister. The second outer wall can include a second end configured to support the canister on a surface. The canister can also include a sealed vacuum cavity forming an insulated double wall structure between the first inner wall and the second outer wall. The insulating container can also include a spout adapter having a spout channel extending through a height of the spout adapter between a bottom surface and a spout opening on a top surface of the spout adapter. The spout opening is sealed with a cap having a magnetic top surface configured to magnetically couple to a docking surface on a grip ring extending around a circumference of the spout adapter between a top threaded surface and a bottom threaded surface. The bottom threaded surface configured to resealably seal the spout adapter to the opening of the canister, and the top threaded surface configured to removably couple the spout adapter to a lid.

In another example, an insulating container may include a canister that has a first inner wall having a first end having a threaded sidewall and an opening extending into an internal reservoir for receiving liquid, and a second outer wall forming an outer shell of the canister. The second outer wall can include a second end configured to support the canister on a surface. The canister can also include a sealed vacuum cavity forming an insulated double wall structure between the first inner wall and the second outer wall. The insulating container can also include an opening adapter that has an external bottom threaded surface to removably couple to and seal the opening of the canister. The opening adapter may also have an internal threaded surface, an external top threaded surface, and a grip ring positioned between the external top threaded surface and the external bottom threaded surface. The insulating container may also include a plug structure that has a substantially cylindrical top portion and a substantially cylindrical bottom portion. The plug structure may also include a threaded outer surface that is configured to removably couple to the internal threaded surface of the opening adapter. The plug structure may also have a handle that is rigidly coupled to a top portion, and a retention tab that is rigidly/flexibly coupled to a bottom portion of the plug structure. Further, an external channel may extend between a channel top edge and a channel bottom edge of the plug structure. Additionally, the insulating container may include a lid that is configured to be removably coupled to the external top threaded surface of the opening adapter.
